ここからの引用だと、
>Supported Releases
>
>The currently supported Ubuntu Studio releases are:
>
> Cosmic Cuttlefish 18.10 until July 2019 (release notes)
> Bionic Beaver 18.04: until January 2019, community support & updates until April 2021 (release notes)
> Xenial Xerus 16.04 LTS: until April 2019 (release notes)
こうなっているので、Ubuntu Studio 18.04 を入れるべきたと思った次第。
